Y* plicable Las a bearingV for the shaft of aconi [Veyer running in abox open at thetop; and may therefore be said to have for yone of its'objects to produce `a bearing for this purpose f 'which willtake'upfthe minimum amount of space in the box and `permit adjustmentandab Figure l'is a transverselsection,through a j replacement of the.actual bearing 'elements inrll^ i Y asimple manner' and without first`disconnectf ing the conveyer or lrequiring' the bearing` p ypedestal tobe disturbed,'and which will per y, mit the oonveyer to be removed fromthe box j 20' without disturbing 4 the 'bearingY `pedestal ordiscontinuing the conveyer sections. y

'A-'singl'e boltVv device isfemployedfto supportk the-bearingbl'ock,hold the cap in place,and f provide adj ustment-fo'i` taking up wear.VThis olt, indicated atv 14, yextends along the' sloty 8 "inthe"pedestaliand has iat its lower o rinner endf fan. arin 15 that'underlies'V the bearing b looklv` The extreme end "of theV arm yispref- I erably bent up, as' indicated iat 16,@and is entered in a.pocketor recess 1.7 in the bottom face of the lbear-ing block, wherebyseparation of the bolt"`from thebearing block through a lateralfmovement wi'llbe" prevented asllong as'whatmay be termed the' projeotionon the vboltrem'ains inthe socket in the underside of thebearingblock.V The bolt extends up through the vflange l9 and throughV-v anopening in that part'jof .the eapfthat `overlies the Y iange. On theupper end of the bolt is a Y nut 18 which `preferably has a conicalunder Vface 19 fitting into a correspondingly shaped seat in the bearingcap.

WhenY theY parts are assembled. as shown,

and lthe nutistightened, the bearing block is drawn up against the shaftand the bearing cap is drawn downwardly or inwardly against the flange'on the pedestal.. After thefcap has beenV drawn firmly into anengagement-withy l the flange it can move no farther, and, `there-Vfore, any further relative movement between the cap andthe block must bethrough a.. Vmovement of the block along the pedestal.

.. Therefore, as wear takes place,inuse, the slack isv taken :up bytightening the nut. and.

drawing the bloclrupvvard.V

When'it is necessary to renewv the bearing,V

Vall that need be done.` is to lunscrew. the single lnut, lift off thecap,Vv andthen raise the oonl'veyer'shaft by ,lifting the screw outthrough the topvof the. box; thus eiposingthebearing.y
